Cometic GM LS1 SB 4.130 inch Bore .036 inch MLS Head Gasket

Cometic Gasket is well-known for making durable sealing solutions, and their Multi-Layer Steel (MLS) head gaskets are a prime example. This particular gasket, part number C5317-036, is built for GM LS1 engines and features a 4.130-inch bore with a compressed thickness of 0.036 inches. It's designed to handle the demands of high-output engines, making it a solid choice for rebuilds or performance builds.

What makes these MLS gaskets stand out is their construction. They use multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to prevent corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This design means you don't need to use any extra sealants, and it works well whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can handle the shearing forces between different metals.

This gasket fits a wide range of GM vehicles, including models like the Chevrolet Corvette, Cadillac CTS, and Buick LaCrosse. It's a well-built component that helps ensure a strong seal for your engine.
